Nuestra Señora de la Asunción (also known as Catedral de la Campina, Spanish for "Cathedral of the Countryside") is a Roman Catholic church in Bujalance, Andalusia, southern Spain.
It originates from the church of Santa Maria, which was built above the medieval mosque, near the town's Alcazaba, after the area had been conquered by Ferdinand III of Castile.
The Gothic cross-vault ceiling is the oldest part of the church.
Next to the altar is a small hexagonal chapel in Baroque style, from the early 18th century.
Other artworks include the Roccoco case by the Cordoban goldsmith Damián de Castro, a large canvas of the Battle of Lepanto and a side Baroque portal in pink marble.
